INSULATED SUPPORT FOR ELECTRICAL CONDUCTORS.

Application filed November 15, 1917.

'1 b all who 111 it may concern Be it known that we, Louis S'rnmunnenn and GUY HILL, citizens of the United States,

and residents, respectively, of the borough.

of Brooklyn, county. of kings, city and ,State of New York, have jointly invented certain new and useful Improvements in Insulated Supports for Electrical-Conductors, of which the following is a specification.

Our invention relates particularly to insulated supports for mounting inductance coils in radio apparatus, said supports or mountings being constructed entirely of insulating material.

One of the objects of our invention is to construct the mount for the conductor forming the coil entirely of insulating material, no metal being utilized in the construction of the mount or support other than the metal of the coil itself.

Another object is to provide a construction by means of which a mount may be formed and the coil embedded in and secured to the mount at a single molding operation.

Another object is to provide a solid support consisting entirely of insulating ma terial provided with ventilating means-adjacent the coil, to provide for rapid selfcooling of the same.

Another object is to provide a disk or sheet of insulating material having an integral spiral ridge, projecting from either one or both surfaces of the disk and within which ridge is embedded and secured the spiral coil.

Another object is to so construct the mounting that the coil may be conveniently and economically put in place and securely mounted in the insulating material during a single molding operation.

Other objects will appear from the heroinafter specification and claims.

Referring to the drawings, in which similar characters indicate the same parts in the several views:

Figure 1 is a plan view of an embodiment of our invention.

Fig. 2 is a section partly broken away on line 2-- 2 of Fig. 1.

Fig. 3 is a section partly broken away similar to that shown in Fig. 2 showing modified means for mounting an inductance coil and securing it in place.

Fig. 4 is a sectional view of a structure Specification of Letters Patent.

Serial No. 202,113.

otherwise similar to Fig. 1 illustrating an insulating support, on each side of which is secured an electrical conductor.

Fig. 5 is a perspective view of a broken section of a form of electrical conductor.

Referring to the figures, the insulated.

support 10 is generally in the form of a plate, slab or disk.

The disk orplate 10 of insulating material forming the support is provided with a ridge. whlch 1s spiral in shape, pro ect1ng from and integral with the surface of the disk, and

to this ridge is secured or anchored a portion of the coil. The ridge is larger at its base than at its top, and there is a surface of insulating material 17 at the top of the ridge provided on both sides of the coil 13. Several series of ventilating holes 14 extending in radial lines, each hole being situated between volutes of the ridge, are provided in orpier to afford ample ventilation for the C01 is molded at one edge into the ridge of insulating material and is held or anchored The spiral coil 13 forming the conductor therein by reason of the fact that the plastic insulating material during the molding operation passes through the perforations 15 in the edge of the coil 13, as clearly shown in Figs. 2 and 5.

As has been said, in making the structure embodying the invention, a coil is secured to the disk and anchored thereto during the molding operation.

In Fig. 3 we have shown a modification in which the coil 13 is molded into the body of the disk between spiral ridges 20, each volute of the coil being situated between or intermediate of two volutes of the integral ridge. In some instances, as shown in this figure, we provide anchoring projections or corrugations 16 extending from the sides of the coil into the insulating material for the purpose of securely fastening the coil to the insulating material.

As shown in Fig. 4.- the electrical conductors may be secured to each side of a supporting disk or plate; in other words, the structure is such that one side of the plate is practically a duplicate of the other.

Our invention may be readily assembled and quickly constructed at a minimum cost, inasmuch as the entire structure may be formed and assembled at one molding operation.

Any suitable insulating material may be used in making the structure described, but we prefer to use that. insulating material known in the art as electrose.

As changes of construction could be made within the scope of our invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described, a plate or support of insulating material, a ridge or projection spiral in form, integrally connected to said support and a conducting coil mounted in the upper face of said projecting ridge.

2. In a device of the kind described, a plate or support of insulating material provided with a spiral ridge projecting from one face thereof, and provided also with a ventilating aperture between the volutes of the ridge, and a metal coil a portion of which is embedded within and secured to said ridge.

3. In a device of the kind described, a plate or support of insulating material provided with an integral spiral ridge extending from one face thereof, and a metal coil a portion of which at one edge is embedded within and secured to said ridge.

4. In a device of the kind described, a

plate or support of insulating material, a.

conducting coil having a series of holes therein near an edge thereof, the said insulating material surrounding the lower edge of the coil and passing through the aforesaid openings.

6. In a device of the kind described, a plate or support of insulating material, a

ridge or projection spiral in form, integrally connected to'one side of said support a conducting coil mounted in the upperface of said projectingridge.

'7. In a device of the kind described, a plate or support of insulating material, a conducting coil and an insulating means each of spiral formation and each projecting from the face of'said plateonsupport, theconductingcoil being exposed above the surface of the insulation.

In witness whereof we have hereunto set our hands at the borough of'M'anhattan, city and State of New York, this third day of November, 1917.
